[mrtg] run "RRDtool graph" from windows cmdline on file.rrd created by MRTG

[Petr Lázňovský]

> When MRTG creates an RRD file, it will always create two DS (called ds0 and ds1, corresponding to octets IN and OUT) and eight RRAs (corresponding to d/w/m/y in AVG and MAX).  You can see this by using 'rrdtool info file.rrd'

> So, your example will not work because you are looking for a DS called 'traffic'.  Try this instead:

> DEF:traffic=file.rrd:ds0:AVERAGE


Thanks Steve. Now it does not produce error message (errorlevel 0), but does not produce any graphs also. I am use following command:

rrdtool graph graph.png --start=-86400 --end=-300 DEF:traffic=file.rrd:ds0:AVERAGE

Can you tell me what parameters are mandatory? I find with google few exaples with many, many parameters, but I want to experiment with minimum parameters as possible until I am able to create any graph. Have RRDtool any 'debug' mode? Something like "mrtg --debug=base,snmp,..."
